NumberFormatInfo.InvariantInfo Property

Gets a read-only NumberFormatInfo object that is culture-independent (invariant).

Namespace:  System.Globalization
Assemblies:   mscorlib (in mscorlib.dll)
  System.Globalization (in System.Globalization.dll)

'Declaration
Public Shared ReadOnly Property InvariantInfo As NumberFormatInfo

Property Value

Type: System.Globalization.NumberFormatInfo
A read-only object that is culture-independent (invariant).

This NumberFormatInfo object returned by this property does not change, regardless of the current culture. It represents the formatting conventions of the invariant culture, which is a culture associated with the English language but not with any country/region. The invariant culture is used in formatting operations that are culture-independent or that produce result strings suitable for display across multiple cultures.

The following example displays the default property values of the InvariantInfo.
